Experimental Testing of the Efficiency of Fast Projective Adaptive Algorithms

Abstract

The article presents the basic relations for correcting sampling estimates of the correlation matrices of adaptive algorithms for detecting the weakest signals in complex interference conditions. The proposed algorithms were used to process field data obtained from a multielement planar array deployed in a maritime zone at a depth of 200 m in coastal wedge conditions. The paper describes the method for processing field data and presents the results of constructing direction-finding reliefs for the case of more than 25 maritime navigation sources in the field of view. It is demonstrated that adaptive algorithms aimed at detecting the weakest signals can yield better results than those obtained by classical adaptive and nonadaptive algorithms.
